CABLE CAR.

Application-med November 25, 1927. Serial No. 235,647.

An object of the 1nvent`on istoy provide a car truck havingaipluralityof drumsy rotatably mounted thereon andl operated through apower plant carried bythe truck,l

and about which a stationary cable may be arranged with its endsanchoredV at -the opposite endof a railway and adapted through thefrictional engagement of the cable with the drum to cause the forward orrearward movement of the car upon therotation of the drum. Y Y

A .further object is to provide brake beams for certain of the drumsadapted t0 secure the same against rotation, the frictional engagementbetween the cable and the drum when idle rserving to retain thel caragainst movement. n u

A further object ofthe invention is to form a gear wheel integrally witheach of the drums and arranged for engagement with each otherforsimultaneous rotation of the drums, said drums being arranged in adouble row along different horizontal planes with thexcable carriedthereupon, with the respective rows of drums mounted for rota tion inopposite direction, whereby through such arrangement to enable thepositive frictional engagement between the cable and the drum foroperating the car without any lost motion. p

. A still further object is to provide an apparatus of this character ofsimple and practical construction, strong and durable, ef-

icient and reliable in performance, rela-` tively inexpensive tomanufacture and operate and otherwise well adapted for the purposes forwhich the same is intended.

Other objects and advantages reside in the special construction andcombination of the various elements comprising the invention, referencebeing had to the accompanying drawings forming a part hereof, whereinFigure 1 is a top plan view, Y

Figure 2 is a view in side elevation,

Figure 3 is a vertical transverse sectional view and Figure 4 is avertical transverse fragmentary sectional view through one end of thecar showing one of the cable guide pulleys arranged at the end thereof.Y

Referring now to the drawings indetail, the invention comprises a cartruck comprisor lum-A lis reversed. y t

The traction for the 'car is derived'through ing `a horizontallydisposedframe indicated at 5 4mounted uponl a pair of truckwheels 6 ateach endfor travelling upon rails 7. Y

The yplatform lincludes a plurality of spaced ,parallel longitudinallyextending.v ,frame members 8 disposed intermediate y.the sides thereof,thev upper edge of saidframe members forming a supportlfora plurality ofbearing brackets 9 forrotatably mounting shafts 10 `extendingtransversely of the'- car and upon each of which cabledrums 11 arerotatably supported.l

The lower edges of the frame membersSi.

also provide means for attaching a plurality of bearing brackets 12forming a mounting for a series of lower shafts 13 upon which drums 14are rotatably carried.

At one side of each of the drums 11 and 14 are formed spur gear wheels15, the gears of the upper and lower sets off drums being engaged forsimultaneous Yoperation with each other. By this; arrangement .theupper.

row of drums are disposed for rotation in an opposite Ydirection fromthe lower row, of drums as illustrated by the directionv shown in Figure2 of the drawings. Each of the upper shafts 10 `extend toward one4 sideof i Y the car, the intermediate shaft havinga relatively enlargedgear'16.' keyed for .rotation therewith and constituting a.V .drive gearforconnection with apower plant of anysuitable character mounted on the carand by means of which the various gears and drums may be operated. v

The upperishafts 10 at each side of the center shaft are provided withbrake drums 17 having brake bands 18 arranged thereabout in brakingrelation therewithV and operatively connected by brake rod 19`which isattached to a brake lever 20 mounted upon a support 21 disposed betweenthe drums 17. As illustrated in Figure 2, the brake'rods 19 extend inopposite directions from the lever 20 and are attached at opposite'sidesof the pivot 22 of the lever so that the movement of x the lever in onedirection will operate the rods in opposite direction. j In order toenable the brake bands 18 to be applied simultaneously through theoperation of the lever in a predetermined direction, the mounting of thebrake band on the respective drums 17 -Y tending between a pair ofhorizontally disposed guide pulleys 24 mounted at each end of the carand then partially wound alternately about the upper and lower sets ofdrums. To accomplish the proper winding yof the cable about the drums inthe manner indicated, the upper and lower sets f drums y drum and backaround the second lower drum and so onthroughout the device until eachof the drums are partially engaged by the Vcable in the mannerindicated.

It will be apparent that upon winding the cable about the drums in themanner indicated and by creating` a .suitable tension upon the cablethat a positive gripping action will occur between the cable and thedrums resulting in the movement of the car in a predetermined directionupon the operation of the drums. Y

Y Furthermore upon the stopping of the drive means for the drum andapplying the brakes through the lever the friction engagement betweenthe drums and the cable will serve to retain the carin position againstmovement and thus enable the car to be held against movement even uponsevere grades.- Cable cars constructed'in accordance with our inventionare admirably adapted foruse in transporting logs, lumber and otherheavy material over grades at a minimum cost of construction,maintenance and operation.

Itis obvious that the invention is susceptiblek of various changes Vandmodifications, without departing from the spirit or scope of theinvention or sacrificing any of its advantages, and we accordingly claimall such formsof the deviceto which we are entitled.'

Having thus described our invention, whaty we'claim as new is: Y v

1. In an apparatus of the class described, a vehicle having a pluralityof horizontally disposed rows of drums rotatably mounted thereon andoperatively connected with each other and the stationary cable woundabout each of said drums.

2. In an apparatus of the class described7 awheeled vehicle,anupper andlower row of drums rotatably mounted thereon, gears attached to each ofsaid drums and mounted forengagement with each other for simultaneousrotation, the upper row of drums being arranged for rotation in adirectionop# posite from said lowerfrow of drums, one of saidv drumshaving a drive gear4 connected therewith, braking means operativelyengageable with a pair of said upper drums and a stationaryy cableengaging each of said v drums. Y

8. In a cable car of the class described, a car platform, car wheels forthe same,a plurality of cable drums rotatably mountedv upon the upperand lower edges of the platform and disposed in staggered relation withres' spect to each other, gear wheels formed on each of said drums, theupper gear being arranged for engagement with the lower gear forsimultaneous rotation of the drum, said upper and lower drums beingdisposed for operative rotation, a drive gear connected with one of theupper drums, brake means operatively engageable with a pairof the upperdrums, a stationary cable, cable guide pulleys mounted at each end ofthe car, said cable being arranged about said upper and lower drums inalternate arrangement.V

In testimony whereof we aiiix our signatures; l
